=============DEVICE DESCRIPTION================
rom=pixel experience A12 rom
recovery=pixel experience's custom recovery.
ram=6GB
processor=snapdragon 600 series (forgot the variant name)
=================Conditions====================
So, i have been using this device for over 4-5 months on this rom as an daily driver, it was working fluently with no issues whatsoever, Mic was a bit glitchy. on an random weekend as usual before going to sleep as the device was on low battery i still remember it being at 6%. i plugged it into an wall outlet to charge and went to sleep. fastforward to the next morning the device is completely dead with no activity on plugging in or out the charger. no vibration or display of any sort, fast forward a week i checked the battery voltage which specified that it was at ~4.0v meaning the battery was charged. which only meant the device was dead.
================RESOLUTIONS==================
So, as the device wasn't turning on fastboot mode would obviously didn't worked. disconnecting and reconnecting the battery didn't worked either. HOWEVER!!, i was able to boot into downlaod/EDL mode using the on board joint on the device and as expected it popped up in device manager meaning it had some life in it, so i went on to use qfil to flash the stock rom but it after flashing the phone never turned on, repeating the step didn't helped. as it went back to it's lifeless state.
now, i want to get this device back to its working state but just can't get it to work. the display probably isn't the fault as there should be an vibration on connecting an charger or rebooting the device.

My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).
I I bought the phone from google 1 week ago, in the early days works well. But then when I flash franco kernel finds phenomenon if I do not connect with computer or charger, the phone crashes, I tried to flash a different kernel, flash CM.10 still crashes when not charging or connecting to computer. I also tried to flash stock and unroot, but still did not fix the error. I now no longer in the U.S., so I can not warranty equipment.
I think my battery is fine, when i discharging, cpu-z show battery 3940mV, but 3 minutes later the phone hangs, the sreen still on, and it will on until battery down, but no response when touching, push button or connecting computer again.
I really need the help. please
Hey all;
Issue 1 : Its almost impossible to turn on.
The times I cannot get it to turn on it also doesn't show that the phone is charging when plugged in (no battery on screen, no led indicator).
If I reinsert battery a few times whilst plugged into a charger it will sometimes work sometimes will not (I've tried multiple batteries on known working charger)
I know when it has worked as the phone vibrates when battery inserted randomly and screen shows the battery charging symbol, then I am able to also turn it on normally.
Issue 2: When charging phone it becomes too hot to touch on the front glass about 1/4 below the earpiece
This is with the phone switched off; with it turned on; same thing but it never gains charge. (fresh ROM flashed, first boot, no connections, sim or wifi)
It also becomes hot when plugged into charger without the battery inserted; assuming strange processor issue?
I tried to charge it from 10%, it reached 35% before I unplugged it as I was concerned the phone would burst into flames; it had become untouchable/almost scalding on the front glass and the battery was absorbing a lot of the heat.
Issue 3: Wifi will not switch on.
Maybe problem with the processor also? although I did not attempt this on a few different stock roms yet.
More details:
So far I've flashed a stock ROM (actually I’ve tried 3 versions so far, two KitKat and one Lollypop); including flashing correct PIT files with each and using NAND erase all just to see if it would help.
I am using Odin 3.09 with good success; I’ve never had a write issue and it behaves itself very well always detecting the phone instantly in boot mode without fail. I've succeeded with all odin flashes of stock roms and booted each one without too much trouble.
The power drain is sufficient that the phone will only stay turned on for a few hours right after a fresh flash (e.g NO user apps; nothing; no sim; no Wi-Fi; NOTHING); after which I have to swap batteries with another (I'm using a working S4 to charge these).
Thanks to all.
So earlier this week, I was using my phone with Google Maps like usual. I plugged in my vehicle USB port to the phone to save battery. I had +50% on the phone and 1A USB port. So after like 5 minutes of it being plugged in, my phone just turned off. I tried turning it back on and all I get is the boot screen, then AXON shows, and puff... Phone off again. I tried booting into recovery but phone turns off before TWRP finishes loading. Phone doesn't seem to be charging. Tried different cables and charger to charge phone but nothing. No charge light. Seems like battery is dead because the phone turns off during boot and battery not charging.
Nothing seems shorted. Phone been working great for weeks before this. BL unlocked, Debloated stock, TWRP. Any ideas other than sending back for warranty? Luckily I still have my S7 as primary but I had my Axon for primary for my trip for real world daily use. Needles to say, photos and videos are wanted off the phone.

Have you tried going to bootloader mode by holding power and volume down
If the battery has died, then the phone wouldn't turn on is my thinking as everyone you then it on it eats some vattwry
You didn't mention specifically, but have you tried using the factory wall charger & cable and leave charge for like an hour?

Original charger but with certified Micro-b/USB-C cable I've been using for weeks between my S7 and the Axon.
So I left the phone alone for the last few days as I was busy at work and Just didn't feel like messing with it when I got home. I tried to turn the phone on but battery was dead. The quick flash of red led was the indicator trying to power it up. So I used my Samsung charger as it was right there and the original ZTE cable. Phone lights up charging and so I left it as is to go to work. I get home, the green led is lit, so I'm hoping my phone will power up now. Nope, right back to my original issue. Power on phone, gets to Axon logo then eventually turns off or goes black screen. I tried booting into recovery but turns off before fully loading. I try to charge phone again but no led indicator.
So later today, I'm going to try to boot into fastboot and try the new TWRP recovery. Maybe it was enabling r/w on system that caused this. I had downgraded to unlock bootloader and then installed ZADmix. I've been usuing it nonstop for 2 weeks with no issues. I have xposed installed so I know rebooted a few times to get everything working and it never turned off since then.
Really frustrating as that's the phone that had my pictures on it.
Hi @RoninBlackSoul, so what did you end up do ? Have you found any way to bring back the Axon from the dead or sent it back to ZTE for repair / replacement ? Same thing just happened to me, and for me Axon 7 is my primary phone ... if the phone is really dead ... will neve buy another ZTE phone ever !!!

Honestly not sure what did it. After battery drained, plugged it in to charge for 2 or 3 days. Then remembered some note about enabling write access in TWRP (something like that) would cause bootloops. Which is weird, rebooted the phone a few times when it was working.
Any case, I reflahed the recovery/bootstack in EDL and got my phone back. Been working great 5 months now

@RoninBlackSoul, thanks for the feedback.
Got mine working also, my phone was not charging at all. After suddenly rebooting and battery went dead fast, phone was not able to charge for about two days. After which, suddenly started working again, was able to charge and works normally now. This is weird. From my point of view this could be: 1. some sort of auto-protection perhaps or 2. an actual hardware design issue that manifests at random (for some after few weeks or months after purchase). For the 1 point: I was using a non original cable using the original charger, and the USB type c plug was hot at the time the issue occurred. Perhaps due to that heat some protection mechanism manifested that got reset after phone was completely out of juice. Will use only original cable with the Original Fast Charger from now on, as the usb-c plug of the 3rd party cable was fine with a normal charger (non QC3). Hope issue will not manifest again or, Axon 7 will be my last ZTE device ...

I only use good chargers rated for QC or 2/2.4 amps like samsung, anker, aukey. Haven't had issues since. Plus certified type-c cables at all times

So. My phone has this problem, and its pretty weird (IMO). It is possible that it is a hardware problem.
I going to work and I dropped my phone. Didn't think much of it. The phone worked fine for several hours. It started around 40% and only declined somewhat, until about 2-3 hours later where it dropped rapidly to 6%. It was in my pocket when it dropped. I figured at the time that I had just forgotten to turn the screen off, so it drained much more battery. I then plugged it in, and it charged for a little while on a non-turbo charged cord, getting to 21% (which is what it said when it was off). After I turned it on however, it was only at 12%. I didn't bother with it at the moment, but after about 5 minutes it dropped to zero in about 5-10 seconds from when it started dropping. This was concerning, but I had to go back to work so I plugged it back in. When I came back and rebooted it showed 11%, and it stayed at 11% for several hours while I was using it, even though I wasn't charging it. Then randomly it dropped super quickly and died. I turbo charged it overnight. In the morning I booted it up and it immediately shut down claiming there was 0% battery life. It will not boot up without being plugged in. This goes on.
Usually, I charge it for a while and it will give a higher number than it will say when it boots up. It sticks at that boot up number for longer than it should, then dies rapidly. Occasionally it will boot up to be 0% and immediately die. I have tried turning in on and off again (without it dying) and it wont turn back on claiming too low of power regardless of how charged it said it was before. I have tried various charging cables and wall outlets. I have tried several battery repair apps, which did nothing. I was going to try and do a root version, since I figured that would be better but cannot root it. (Using adb to sideload comes up with an error (signature verification failed), trying to flash twrp fails (pre-flash validation failed) and normal root methods fail.) Oh yeah, and I've also factory reset it a few times.
So it seems to me that it's a software problem, namely the battery driver, since it appears to be charging and holding a charge for the most part, but then shutting down randomly due to the driver saying it is at 0% battery life. Alternatively, it could be a problem with the battery or charging port, although nothing seems to be wrong with the charging port visually.
Also potentially of note is that my normal turbo charger, when plugged in, puts a lightning bolt icon in the battery symbol, but on battery usage it says not charging. This could also be the chargers fault, since it had begun to fail previously (only working at certain angles) but it worked earlier the same day and now doesn't.
I didn't install any new updates to the OS or installed any new apps before this occurred either.
Any idea whats going on and how to fix it?
EDIT: I've been trying to look up and see if there was a driver or something for the battery that I could reinstall but I couldn't find anything. So, I ordered a replacement battery of Amazon. Now the question becomes will that fix my problem if I replace the battery?
Think so this might solve your issue ,but getting it checked before ordering would be wise.
Going through your rooting steps , i didnt see that you unlocked your device thats why you are getting errors of signature verification failed.
There is no separate battrey driver for Android its the part of OS itself so you dont need to mess up with that area
Uh... yeah well, Droid Turbo 2's can't root. It wont work. The bootloader is locked up tight, even if you select it in developer options it does nothing.
